Connecting trading with settlement and delivery
I contribute to Keyvangold’s backend alongside other engineers. The platform connects pricing and identity verification with rial and gold wallets, payments, settlement, inventory, and physical delivery.
My work includes APIs and database workflows across these areas. A wallet operation also needs to make sense to the people handling settlement, inventory, and delivery, so the backend connects customer-facing actions with operational records.
Making transactions traceable
I contribute to financial ledgers, role-based permissions, audit logging, Excel reports, and Persian invoice PDFs. These give business users ways to inspect and explain an operation after the immediate transaction.
Balances, transaction records, invoices, and exports serve different readers. Keeping those views connected is part of the backend work, alongside the trading APIs themselves.
Maintaining an operating application
The ongoing engagement also includes database migrations, Docker deployments, Nginx configuration, and production maintenance.
Keyvangold and GBT Market are separate projects. This page describes my collaborative Keyvangold contribution; GBT’s chart and wallet implementation has its own technical walkthrough.
